This has allowed us to create a more comfortable life for ourselves as well as helping us to make all kinds of useful materials at a low cost. One […]
Read more "Goldsmiths’ 2013"Vulcanisation of latex Activity: The point of the experiment is to look at the modification of the properties of a material made from a natural, renewable resource. Sulphur is added to a suspension of natural latex and the mixture is heated in a process known as vulcanisation. Background: Latex (also known as natural rubber) is […]
Read more "Goldsmiths’ 2013"Making Plastic from Milk! Milk contains a protein called casein—from the Latin word “caseus” meaning cheese. Casein is a polypeptide which is relatively insoluble in water. Milk is white because of the tiny particles of casein suspended in the solution—not dissolved. This experiment uses the casein present in milk to make a natural plastic. Materials: […]
